Alger, Chicago, 11]., assignor to Configured Tube I 2 narrow and compact when viewed from the top. height, length and upward convergence of the sidewalls 24 regulate the length, width and the thickness of the flame. The inclination of the bottom deflector wall 22 may be varied to change the upward inclination of the flame.

It will be seen that the flame deflector body is posi-, tioned directly in front of the burner port 16, and is spaced upwardly from the port by a mounting portion or leg 26' which extends between the body 20 and the burner tube 14. As illustrated, the mounting leg 24 is formed inte-' grally with the'deflector body 20, and is arranged to form I of the burner tube 14.

Another object is to provide-a new and improved flame :defl'ector having means for producing small retaining flames extending laterally from the base of the main flame. A further object is to provide new and'improved flame deflector-s that may be employed on a series of burners arranged in parallel, spaced relation, so that the entire series of burners will become lighted in sequence, if the first burner in the series is ignited.

Further objects and advantages of the present invention a continuation of the bottom wall 22 and portions of the sidewall flanges 24. The inner end of the mounting leg 26 maybe welded or otherwise secured to the under side In order to form small stabilizing or retaining flames at the base of the main flame 23, the deflector body 20 is provided with a pair of wings or ears 28 which project laterally from the inner ends of the sidewall flanges 24; Thus, the ears 28 extend in opposite horizontal directions from the sidewalls 24.

The effect of the ears or wings 28 is to pick up and deflect small portions of the fuel and air mixture in lateral directions, so as to form small laterally directed flames adjacent to the base of the main flame 23. These small flames have a stabilizing effect on the main flame and thus will appear from the following description, taken with the accompanyingdrawings in which: I Figsl is a perspective view showing a burner equipped with a flame deflector that will be described as an illustrative embodiment of the present invention. 1 -Fig. 2 is a small scale elevational view of the flame de flector, showing the pattern of the flame produced by the i 4 burner, when operating without forced draft.

Fig. 3 is a top view of the flame deflector.

Fig. 4'is the side elevational view of the deflector.

Fig. 5 is a front or end view of the flame deflector.

It will be seen that Fig. 1 illustrates a flame deflector or spreader 10 for use. in connection with a gas burner 12, which may be of a known type having a mixture tube 14 adapted to receive gaseous fuel and air, and to discharge a mixture of the fuel and air through a port 16 in the end of the mixture tube 14. In this case, the mixture tube 14 is horizontally directed and is formed with anannular flange 18 turned inwardly at'a'n acute angle around the burner port 16.

The illustrated flame deflector 10 has a body portion 20 which is generally channel-shaped. Thus, the body 20 The side walls 24 are quite closely spaced, with respect to the length of the flame deflector body 20. Thus, the

bottom deflector wall 22 is narrow and quite elongated.

3 As shown, the side walls 24 are bent toward each other so that they converge upwardly. In other words, the space between'the sidewalls 24 tapers upwardly. The

height of the illustrated sidewalls 23 is relatively great with respect to the space between the sidewalls.

iThe result of this arrangement of the flame deflector body 20 is to produce a main flame 23 which is deflected upwardly and spread out vertically so as to be wide when viewed in elevation as in Fig. 2, the flame being quite I tend to prevent the main flame from being blown out. The ears 28 are shown as being bent outwardly at right angles from the sidewalls 24, but this angle may be varied to change the shape and size of the retaining flames; Thus, the ears 28 may be bent inwardly, toward the burner tube 14, so as to reduce the size of the retaining flames.

Because of the lateral deflection of the fuel air mixture, a series of burners like that shown in Fig. 1 may be mounted side by side in a horizontal series. All of them may be lighted by lighting the first burner-in the series. The burners will light in sequence due to the formation of the laterally extending retaining flames on each burner. This characteristic of the flame deflector is highly advantageous where it is necessary or desirable to use two or more burners in a gas appliance.

It will be noted that the height of the side flanges 24 is considerably greater than the diameter of the mixture tube 14 so that the flanges definitely tend to confine the mixture as it is deflected upwardly by the inclined lower wall 22. As illustrated, the lower wall 22 is tapered outwardly and the sidewall flanges 24 are slightly conver gent in an outward direction. This tends to have a narrowing eflect upon the flame. Various modifications, alternative constructions and equivalents may be employed without departing from the true spirit and scope of the invention, as exemplified 'in the foregoing description, and defined in the following claims.
